In order to design the fir filter impulse response sequence is finite, so use the finite length of the sequence h (n) to approximate the infinite sequence

But thousands of FIR filter with impulse response sequence is a finite-length, so you want to use finite-length sequences of h (n) approximation of infinite sequences

But must count the FIR filter impulse response sequence is finite, therefore must use finite sequence h(n) to approach the infinite long sequence

The need to take into account the FIR filters sequence is a response to the beat of long limited, so it is necessary to use a limited long sequences of H(N) to approaching infinite length of sequence

But thousands of FIR filter with impulse response sequence is a finite-length, so you want to use finite-length sequences of h (n) approximation of infinite sequences
